Description

Technical Field

[0001] The utility model relates to the field of logistics packaging, in particular to a bracket structure for installing a machine for producing buffer mat materials. Background Art

[0002] At present, cushioning materials are generally produced by paper cushion machines, and some styles of cushion materials are also produced by bubble pressing machines and honeycomb paper machines. Since paper cushion machines have a certain weight, it is laborious to move them, and they are also easy to fall and be damaged.

[0003] Existing paper pad machines are generally equipped with a bracket for easy movement, and in order to maintain stability, three, four or more legs distributed in a plane are installed at the bottom of the bracket, so that the paper pad machine is not easy to tip over during use. However, during transportation for external sales, the paper pad machine and the bracket need to be packaged. However, since the bracket has multiple legs, the bracket will occupy more packaging space and will also cause more gaps in the packaging space. The utilization rate of the packaging space is low, and the packaging loss used to fill the gaps in the packaging space is also relatively large.

[0004] Therefore, how to overcome the above technical defects is a technical problem that needs to be solved urgently by those skilled in the art. Utility Model Content

[0005] The purpose of the utility model is to provide a bracket structure to solve at least one of the above technical problems.

[0006] According to one aspect of the utility model, there is provided a support structure, comprising:

[0007] At least three legs, one end of each leg is connected together, and at least one of the legs can be folded and turned;

[0008] a support rod, the bottom of which is disposed on the legs; and

[0009] A mounting plate is used to install the paper pad machine, and the mounting plate is arranged on the top of the support rod.

[0010] The support structure of the utility model can be applied to a paper pad machine, which is installed on a mounting plate. The legs can ensure that the paper pad machine remains stable and is easy to move. During transportation for external sales, at least one leg can be folded and flipped. After the legs are folded, the packaging space occupied by the support structure can be reduced, which is convenient for transportation. It can also improve the utilization rate of the packaging space, reduce the gaps in the packaging space, and thus reduce the use of packaging consumables for filling the gaps.

[0011] In some embodiments, the device may further include a connecting plate, at least one rotating member and at least one fixing member, wherein one end of the supporting leg is disposed on the connecting plate.

[0012] At least one leg is rotatably connected to the connecting plate via a rotating member, and a fixing member fixes the leg and the connecting plate together.

[0013] Therefore, when the supporting legs need to be folded and turned, the fixing members fixing the supporting legs are removed, and then the supporting legs can be rotated around the rotating members to realize the folding and turning of the supporting legs.

[0014] In some embodiments, the number of the legs may be four, the four legs are planar and distributed at equal angles, and two of the legs are foldable and flippable.

[0015] Therefore, during transportation, the two legs can be folded and turned over. After the two legs are folded, the packaging space occupied by the support structure can be greatly reduced, which is convenient for transportation, and can also improve the utilization rate of the packaging space and reduce the gaps in the packaging space.

[0016] In some embodiments, the number of the legs may be four, the four legs are in a plane and are distributed at equal angles, two of the legs are foldable and flippable, and the two foldable and flippable legs are distributed adjacent to each other.

[0017] Therefore, after removing the fixing parts of the two foldable and flippable legs, the two legs rotate around the rotating parts and are folded and leaned against the other two legs respectively. Since the two foldable and flippable legs are distributed adjacent to each other, after the two legs are folded, the four legs are in a V shape as a whole, which can greatly reduce the packaging space occupied by the bracket structure.

[0018] In some embodiments, the device may further include a connecting plate, two rotating members and two fixing members, one end of the supporting leg is disposed on the connecting plate,

[0019] A foldable and flippable leg is rotatably connected to a connecting plate through a rotating member, and a fixing member fixes the leg and the connecting plate together.

[0020] Another foldable and flippable supporting leg is rotatably connected to the connecting plate through another rotating member, and another fixing member fixes the supporting leg and the connecting plate together.

[0021] Therefore, when the legs need to be folded and turned, the fixing members fixing the two foldable and turnable legs are removed, and then the two foldable and turnable legs can be rotated around the rotating member respectively to achieve folding and turning.

[0022] In some embodiments, the connecting plate may be cross-shaped, the bottom of the supporting rod is arranged at the center of the connecting plate, and the rotating member and the fixing member are both bolt and nut structures.

[0023] Therefore, the cross-shaped connecting plate can assemble the four legs together, and the four legs are also cross-shaped as a whole, ensuring that the paper pad machine installed on the bracket remains stable. When the legs need to be folded and flipped, the fixing parts (bolt and nut structure) that fix the legs are removed, and then the rotating parts, that is, the nuts of the bolt and nut structure, are loosened. Then the legs can be rotated around the rotating parts, that is, the screw rods of the bolt and nut structure, to achieve the folding and flipping of the legs. After the legs are folded and flipped, the rotating parts, that is, the nuts of the bolt and nut structure, can be tightened to prevent the folded legs from swinging.

[0024] In some embodiments, a bracket for carrying paper materials may be further included. The bracket is arranged on the support rod, and detachable side panels are respectively arranged on both sides of the bracket. The distance between the two side panels can be adjusted.

[0025] Thus, the paper used by the paper pad machine can be placed on the bracket, and the distance between the two side plates on the bracket can be adjusted according to the width of the paper to meet the placement of paper of different widths.

[0026] In some embodiments, a fixing plate may be further included, wherein the fixing plate is disposed on the support rod, the side portions of the side panels are disposed on the fixing plate and are detachably connected to the fixing plate, the bracket is provided with a plurality of slots, and the bottoms of the side panels are inserted into the slots.

[0027] Therefore, according to the width of the paper material, the side panels on both sides of the bracket can be removed, and then the two side panels can be inserted into appropriate slots respectively.

[0028] In some embodiments, the fixing plate may be provided with holes for fixing the paper padding machine.

[0029] Therefore, when packaging and transporting, the paper pad machine installed on the mounting plate can be removed, and then the paper pad machine can be installed on the fixed plate, so that the paper pad machine and the bracket can be packed together as a whole, and there is no need to pack the paper pad machine separately, so as to minimize the packaging space occupied by the bracket structure and the paper pad machine as a whole, and the paper pad machine installed on the fixed plate can further improve the utilization rate of the packaging space.

[0030] In some embodiments, the support rod may be hollow, a height-adjustable adjustment rod is disposed inside the support rod, and the mounting plate is disposed on the top of the adjustment rod.

[0031] Therefore, according to the usage scenario of the paper pad machine, the height of the paper pad machine installed on the top of the adjusting rod can be adjusted by the adjusting rod.

[0032] In some embodiments, at least one adjusting pin may be included, a plurality of first through holes may be provided on the support rod, a plurality of second through holes may be provided on the adjusting rod, the adjusting rod is inserted into the support rod, and the adjusting pin passes through the first through hole on the support rod and is inserted into the second through hole on the adjusting rod.

[0033] Therefore, when it is necessary to adjust the height of the paper pad machine installed on the top of the adjusting rod, remove the adjusting pin and then move the height of the adjusting rod longitudinally. When the height of the paper pad machine is adjusted, pass the adjusting pin through the first through hole on the support rod and insert it into the second through hole on the adjusting rod to complete the fixing of the adjusting rod. The height adjustment of the paper pad machine is very convenient.

[0034] In some embodiments, it may also include at least one adjusting pin, a plurality of first threaded holes are provided on the support rod, a plurality of second through holes are provided on the adjusting rod, the adjusting rod is inserted into the support rod, the adjusting pin is screwed into the first threaded hole on the support rod and the end of the adjusting pin is inserted into the second through hole on the adjusting rod.

[0035] Therefore, when it is necessary to adjust the height of the paper pad machine installed on the top of the adjusting rod, remove the adjusting pin and then move the height of the adjusting rod longitudinally. When the height of the paper pad machine is adjusted, screw the adjusting pin into the first threaded hole on the support rod and insert the end of the adjusting pin into the second through hole on the adjusting rod to complete the fixing of the adjusting rod. The height adjustment of the paper pad machine is very convenient.

[0036] In some embodiments, it may also include at least one adjusting pin, a plurality of first through holes are provided on the support rod, a plurality of second threaded holes are provided on the adjusting rod, the adjusting rod is inserted into the support rod, and the adjusting pin passes through the first through hole on the support rod and is screwed into the second threaded hole on the adjusting rod.
